In addition, the heat transfer oil pipe is easily worn out and is not easy to replace. Utility Model Content

[0003] The utility model aims to provide a pole piece preheating roller, which has a simple and reasonable structure, is easy to assemble and maintain, heats evenly, and can save space occupied by the equipment.

[0004] A pole piece preheating roller, comprising:

[0005] A roller body, wherein a first channel extending along the axial direction is provided at the center of the roller body, and a heating cavity is formed on the outer peripheral side of the first channel;

[0006] an oil inlet pipe extending from one end of the roller body into the first channel and being coaxial with the first channel, wherein a gap is provided between the oil inlet pipe and the inner circumference of the first channel, and the gap forms an oil outlet channel;

[0007] at least one second channel, provided at one end of the roller body away from the oil inlet pipe, the second channel communicating with the first channel and the heating chamber; and

[0008] At least one third channel is arranged at one end of the roller body close to the oil inlet pipe, and the third channel is connected with the heating chamber and the oil outlet channel.

[0009] In the above technical solution, the heat transfer oil enters the first channel from the oil inlet pipe, and then enters the heating chamber through the second channel until the heat transfer oil fills the heating chamber, and the overflowing heat transfer oil enters the oil outlet channel through the third channel, and is then discharged. Compared with the prior art, the utility model simplifies the structure of the preheating roller, which is convenient for assembly and subsequent maintenance. By using the gap between the oil inlet pipe and the first channel as the oil outlet channel, the heat transfer oil enters and is discharged on the same side of the roller body, thereby saving equipment space.

[0010] Furthermore, the roller body includes a main shaft, a roller sleeve arranged on the outer peripheral side of the main shaft, and a first blocking member and a second blocking member respectively arranged at two ends of the main shaft, and the heating chamber is located between the roller sleeve and the main shaft.

[0011] In the above technical solution, the main shaft and the roller sleeve are connected by the first blocking member and the second blocking member, so that a heating chamber is formed between the main shaft and the roller sleeve. The structure is simple and easy to assemble. The contact area between the heating chamber and the roller sleeve is large, which can make the target part heated more evenly and improve the preheating effect.

[0012] Furthermore, the second channel and the third channel are respectively provided in the first blocking member and the second blocking member.

[0013] In the above technical solution, when the first blocking member and the second blocking member are connected to the main shaft and the roller sleeve, the second channel and the third channel can be connected to the heating chamber.

[0014] Furthermore, the first channel passes through the first blocking member, and the oil inlet pipe is disposed through the first blocking member.

[0015] In the above technical solution, the first channel runs through the first blocking piece, and the oil inlet pipe is arranged through the first blocking piece, so that the entry and discharge of the heat transfer oil are both located on one side of the first blocking piece, which can effectively reduce the space occupied by the equipment.

[0016] Furthermore, a connecting piece is provided near the first blocking piece, and the connecting piece includes an oil inlet communicated with the oil inlet pipe, and an oil outlet communicated with the oil outlet channel.

[0017] In the above technical solution, heat transfer oil can be introduced into the oil inlet pipe through the oil inlet, and after the heat transfer oil passes through the interior of the roller body, it is discharged from the oil outlet through the oil outlet channel.

[0018] Furthermore, there are four second channels, and the four second channels are arranged at equal angles with the first channel as the axis.

[0019] In the above technical solution, by setting the number of second channels to four, and arranging the four second channels at equal angles with the first channel as the axis, it can be ensured that no matter to which angle the roller body rotates, the heat transfer oil can enter the heating chamber from the bottom second channel by gravity.

[0021] In the above technical solution, there are four third channels, and the four third channels are arranged at equal angles with the first channel as the axis, which can ensure that no matter to which angle the roller body rotates, the heat transfer oil can flow from the top third channel into the oil outlet channel by gravity.

[0022] Furthermore, the extension direction of the second channel and the third channel is perpendicular to the extension direction of the first channel.

[0023] In the above technical solution, the extension direction of the second channel and the third channel is perpendicular to the extension direction of the first channel, so that the heat transfer oil can flow in the roller body under the action of gravity, ensuring smooth flow.

[0024] Furthermore, a rubber plug is sleeved on the end of the oil inlet pipe, and the rubber plug abuts against the inner circumferential surface of the first channel.

[0025] In the above technical solution, the rubber plug can form a barrier between the oil inlet pipe and the inner circumference of the first channel, thereby forming an oil outlet channel, while preventing the heat transfer oil from flowing back in the oil outlet channel, ensuring that the heat transfer oil flows in a single direction.

[0026] Furthermore, it also includes a driving member, which is connected to the roller body and is used to drive the roller body to rotate.

[0027] In the above technical solution, the driving member can drive the roller to rotate so as to roll over the surface of the target part to preheat the target part.

[0028] Compared with the prior art, the utility model has the following beneficial effects: the heat transfer oil enters the first channel from the oil inlet pipe, and then enters the heating chamber through the second channel until the heat transfer oil fills the heating chamber, and the overflowing heat transfer oil enters the oil outlet channel through the third channel, and is then discharged.

[0040] Please refer to Figures 1 to 4In a preferred embodiment, the pole piece preheating roller of the utility model mainly comprises a roller body 1 and an oil inlet pipe 2. The center of the roller body 1 is provided with a first channel 11 extending along its axial direction, and a heating chamber 12 is formed on the outer peripheral side of the first channel 11. The oil inlet pipe 2 extends into the first channel 11 from one end of the roller body 1 and is coaxial with the first channel 11. There is a gap between the oil inlet pipe 2 and the inner peripheral surface of the first channel 11, and the gap forms an oil outlet channel 13. At least one second channel 18 is provided at one end of the roller body 1 away from the oil inlet pipe 2, and the second channel 18 connects the first channel 11 and the heating chamber 12. At least one third channel 19 is provided at one end of the roller body 1 close to the oil inlet pipe 2, and the third channel 19 connects the heating chamber 12 and the oil outlet channel 13.

[0041] During preheating, the heat transfer oil enters the first channel 11 from the oil inlet pipe 2, enters the heating chamber 12 through the second channel 18, until the heat transfer oil fills the heating chamber 12, and the overflowing heat transfer oil enters the oil outlet channel 13 through the third channel 19, and is thus discharged. The overall structure is reasonable and has the advantages of fast preheating speed and uniform heating.

[0042] Compared with the prior art, the present invention does not need to provide a spiral heat transfer oil pipe, thereby simplifying the structure of the preheating roller, facilitating assembly and subsequent maintenance. By using the gap between the oil inlet pipe 2 and the first channel 11 as the oil outlet channel 13, the heat transfer oil enters and is discharged on the same side of the roller body 1, thereby saving equipment space.

[0043] In this embodiment, the roller body 1 includes a main shaft 14, a roller sleeve 15, a first blocking member 16, and a second blocking member 17. The main shaft 14 is formed in a cylindrical shape, and the first channel 11 penetrates the main shaft 14 along the axial direction of the main shaft 14. The sleeve is formed in a cylindrical shape and is arranged on the outer peripheral side of the main shaft 14. The first blocking member 16 and the second blocking member 17 are respectively arranged at both ends of the main shaft 14, and the main shaft 14 and the sleeve are connected by the first blocking member 16 and the second blocking member 17. In specific implementation, the outer diameter of the main shaft 14 is smaller than the inner diameter of the sleeve, so that a heating chamber 12 is formed between the main shaft 14 and the sleeve.

[0044] The main shaft 14 and the roller sleeve 15 are connected by the first blocking piece 16 and the second blocking piece 17, so that a heating chamber 12 is formed between the main shaft 14 and the roller sleeve 15. The structure is simple and easy to assemble. The contact area between the heating chamber 12 and the roller sleeve 15 is large, which can make the target part heated more evenly and improve the preheating effect.

[0045] In this embodiment, the second channel 18 and the third channel 19 are respectively provided in the first blocking member 16 and the second blocking member 17. Exemplarily, the first blocking member 16 and the second blocking member 17 both have a first connection portion 161 and a second connection portion 162 protruding from the first connection portion 161, and the second channel 18 and the third channel 19 are respectively provided in the second connection portions 162 of the first blocking member 16 and the second blocking member 17, and the first connection portion 161 can be connected to the shaft sleeve, and at this time, the second connection portion 162 extends into the inner side of the shaft sleeve and is connected to the main shaft 14. When the first blocking member 16 and the second blocking member 17 are connected to the main shaft 14 and the roller sleeve 15, the second channel 18 and the third channel 19 can be connected to the heating chamber 12, and at the same time, the second channel 18 is connected to the first channel 11, and the third channel 19 is connected to the oil outlet channel 13, which is convenient for processing and assembly.

[0046] In this embodiment, the first channel 11 passes through the first blocking member 16, and the oil inlet pipe 2 is provided in the first blocking member 16. The first channel 11 passes through the first blocking member 16, and the oil inlet pipe 2 is provided in the first blocking member 16, so that the inlet and outlet of the heat transfer oil are both located on one side of the first blocking member 16, which can effectively reduce the space occupied by the equipment.

[0047] A connector 3 is provided near the first blocking member 16, and the connector 3 includes an oil inlet 31 communicating with the oil inlet pipe 2, and an oil outlet 32 ​​communicating with the oil outlet channel 13. In specific implementation, the oil inlet 31 and the oil outlet 32 ​​can be connected to a heat transfer oil storage device (not shown), and heat transfer oil can be introduced into the oil inlet pipe 2 through the oil inlet 31. After the heat transfer oil passes through the roller body 1, it is discharged from the oil outlet 32 ​​through the oil outlet channel 13, thereby realizing the circulation of the heat transfer oil.

[0048] In this embodiment, there are four second channels 18, and the four second channels 18 are arranged at equal angles with the first channel 11 as the axis. By setting the number of second channels 18 to four and the four second channels 18 being arranged at equal angles with the first channel 11 as the axis, it can be ensured that no matter which angle the roller body 1 rotates to, the heat transfer oil can enter the heating chamber 12 from the second channel 18 at the bottom by gravity.

[0049] There are four third channels 19, and the four third channels 19 are arranged at equal angles with the first channel 11 as the axis. There are four third channels 19, and the four third channels 19 are arranged at equal angles with the first channel 11 as the axis, which can ensure that no matter which angle the roller body 1 rotates to, the heat transfer oil can flow from the uppermost third channel 19 into the oil outlet channel 13 by gravity.

[0050] It is understandable that in other possible embodiments, the number and arrangement of the second channel 18 and the third channel 19 can be set according to actual needs, and it is only necessary to ensure that the hot oil can flow from the first channel 11 to the heating chamber 12, and flow from the heating chamber 12 into the oil outlet channel 13.

[0051] In this embodiment, the extension direction of the second channel 18 and the third channel 19 is perpendicular to the extension direction of the first channel 11, so that the heat transfer oil can flow in the roller body 1 under the action of gravity, ensuring smooth flow.

[0052] The end of the oil inlet pipe 2 is sleeved with a rubber plug 21, which abuts against the inner circumference of the first channel 11. The rubber plug 21 can form a barrier between the oil inlet pipe 2 and the inner circumference of the first channel 11, thereby forming an oil outlet channel 13, while preventing the heat transfer oil in the oil outlet channel 13 from flowing back, ensuring that the heat transfer oil flows in a single direction.

[0053] The pole piece preheating roller of the present invention further includes a driving member 4, which is connected to the roller body 1 and is used to drive the roller body 1 to rotate. Exemplarily, the driving member 4 can be a motor, which is arranged at one end of the roller body 1 away from the oil inlet pipe 2, and the driving member 4 can drive the roller body 1 to rotate, so as to roll over the surface of the target part to preheat the target part.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
